Angular corner connecting piece for profiled frame members of multi-sheet insulating glass

Abstract

An angular corner connecting piece for profiled frame members of multi-sheet insulating glass has angularly disposed legs adapted to be inserted into cornerwise adjacent profiled frame members of the multi-sheet glass. The legs include a base plate having a plurality of projecting ribs. The legs are connected by a rigidifying head having walls. At least one spring is connected between each pair of ribs and between one of the ribs and the walls of the rigidifying member and are resiliently deformable upon insertion of the legs into the profiled frame members. The rigidifying head has transverse sealing grooves and pairs of guide ribs.

What is claimed is: 
     
       1. An angular corner connecting piece suitable for use with profiled frame members of multi-sheet insulating glass comprising: a pair of longitudinally extending legs angularly disposed with respect to each other by an angle of 90° and insertable into the hollow crosswise adjacent profiled frame members of the multi-sheet insulating glass, each of said leg members including a base plate having at least a pair of spaced projecting ribs adapted to the cross-section of the profiled frame member and lying transverse to the direction of extension of said legs; and   a rigidifying head connecting said legs into an intergral unit, said head having walls lying parallel to said spaced ribs of said legs, springs extending between said ribs and walls and resiliently deformable upon insertion of the legs into the respective profiled frame member, said walls of said rigidifying head forming sealing grooves in said head defined by sealing lips on said walls, said grooves extending transversely to the direction of extension of said legs, said rigidifying head having an outer surface normal to said walls with an exposed edge inclined by 45° relative to the longitudinal extension of said legs, said head having pairs of guide ribs extending parallel to said sealing lips and enclosing angles of about 45°, respectively, 135° with the edge of said rigidifying head outer surface.   
     
     
       2. An angular corner connecting piece as claimed in claim 1 wherein the upper ends of said guide ribs of said rigidifying head are located in a common plane parallel to said exposed edge of the rigidifying head outer surface. 
     
     
       3. An angular corner connecting piece as claimed in claim 1 wherein said guide ribs lie parallel to the adjacent wall of said rigidifying head.
